I have been thinking about self-hosting my personal photos on my linux server. After the recent backdoor was detected I’m more hesitant to do so especially because i’m no security expert and don’t have the time and knowledge to audit my server. All I’ve done so far is disabling password logins and changing the ssh port. I’m wondering if there are more backdoors and if new ones are made I can’t respond in time. Appreciate your thoughts on this for an ordinary user.
Even if there are nation state level backdoors, your personal server is not a valuable enough target to risk exposing them. Just use common sense, unattended-upgrades, and don’t worry too much about it.
